Once, Albert Einstein, the world-famous scientist, was traveling by train. At dinner time, he went to the dining car.
Menu in hand, he suddenly realized that he had forgotten his glasses in his compartment. He shrugged. Unwilling to go back, he tried his best to identify the fine print. However, his effort was in vain. He returned the menu to the waiter nearby and said, "Would you please read this menu for me?"
The waiter shrugged. Then he murmured to Mr. Einstein, "Sir, I'm terribly sorry. I am illiterate too."
